Feature scope

The new Provisiond config UI enables users to adjust the sizes of the Provisiond thread pools.

This Jira task describes a testing methodology for this specific portion of the new config UI.

Tests should cover the four pools with both sane and unexpected input values:

• Scan threads

• Rescan threads

• Import threads

• Write threads

The default sizes of these thread pools are fairly conservative and are commonly increased on larger systems. Sane ranges for these pool sizes might be:

• Scan and rescan: 10 (default) – 1000

• Import and write: 8 (default) – 100

Upon changing the size of one or more pools and applying the changes, the following must happen on the system:

• The new values are reflected in the /rest/cm/provisiond/default config entry

• The user is presented with a long-lived snack bar element indicating that OpenNMS needs to be restarted for changes to the thread pool sizes to take effect.

Test will be run against 1 Linux variant (more if time permits):

• Centos 8

• Ubuntu LTS

• Docker 

• Centos 7

Related to this story but considered outside the scope of testing for this test task:

• This task is limited to the front-end UI and the /rest/cm/provisiond/default config entry.

• Validating that the Provisiond service daemon does the right thing upon restart is out of scope for this task.

Test environment

No extra dependencies beyond a working installation of Horizon

Automation

If possible this task should be converted to a smoke test that can be run as part of release process.
